A C compiler for DOS. Uploading this on the off chance someone somewhere will need this specific compiler. The disk was packed in with a 662 page manual that was still sealed at the time I purchased it. The Minimum requirements are listed as follows on the back of the manual:
MSDOS or PCDOS 2.0 or later. 256K memory, 2 floppy drives or hard drive recommended. Runs on IBM PC, XT, AT, and compatibles, and IBM PS/2 model 25, 30,50, 60, or 80.
